Ok, I think I understand the idea (I tried Geiger's Snes9x Debugger earlier today, and didn't even know where to start
). I will try (and ask help in a new topic if needed)!
Yes, I was talking about Gradius III on the arcade system.
About the difficulty settings in the first draft of your fast rom patch.
"Elite, master, expert and pro" are not very explicit, don't you think? The names could be switched, no one would tell the difference.
Here are some ideas (maybe good, maybe not):
With 8 levels of difficulty : "easy 3, easy 2, easy 1, normal, hard 1, hard 2, hard 3, arcade".
Or with only 5 levels : "novice, easy, normal, hard, arcade", with novice being the original easy, and easy something between the original easy and normal.
In any case, I feel everything should be unlocked by default, except "arcade", the hardest (keeping the same way to unlock as in the non-modded game).
